Subject: [PATCH 3.18 14/85] selftests: ftrace: Add a testcase for multiple actions on trigger

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Masami Hiramatsu <mhiramat@...nel.org>

[ Upstream commit 25aa50e0ca397a5e5d4d6fcecefa8107877d1dd0 ]

Add a testcase for multiple actions with different
parameters on an event trigger, which has been fixed
by commit 192c283e93bd ("tracing: Add action comparisons
 when testing matching hist triggers").
